ServotronicThe concept
The Servotronic varies the steering force re‐
quired to turn the wheels in accordance with
the vehicle speed. At low speeds, the steering
force is strongly supported, i. e. during steer‐
ing, low force is required. As the speed in‐
creases, the assistance of the steering force is
reduced.
Furthermore, the steering force adapts accord‐
ing to the driving program, so that a direct,
sporty feel and/or comfortable steering is con‐
veyed.
Driving Dynamics Control The conceptThe Driving Dynamics Control helps to fine-
tune the vehicle's settings and features. Vari‐
ous programs can be selected for this purpose.
The Driving Dynamics Control and the DSC
OFF buttons can each be used to activate a
program.

LoadingVehicle features and options
This chapter describes all standard, country-
specific and optional features offered with the
series. It also describes features that are not
necessarily available in your car, e. g., due to
the selected options or country versions. This
also applies to safety-related functions and
systems. The respectively applicable country
provisions must be observed when using the
respective features and systems.
Information WARNING
High gross weight can overheat the tires,
damage them, and cause a sudden drop in tire
inflation pressure. There is risk of an accident.
Pay attention to the permitted load capacity of
the tires and never exceed the permitted gross
weight.◀
WARNING
Loose objects or devices with a cable
connection to the vehicle, e.g., mobile phones,
can be thrown into the vehicle's interior while
driving, e.g.,in the event of an accident or dur‐
ing braking and evasive maneuvers. There is a
a risk of injury. Secure loose objects or devices
with a cable connection to the vehicle in the
vehicle's interior.◀
ATTENTION
Fluids in the cargo area can cause dam‐
age. There is a risk of damage to property.
Make sure that no fluids leak in the cargo
area.◀Determining the load limit1.Locate the following statement on your ve‐
hicle’s placard:▷The combined weight of occupants
and cargo should never exceed XXX kg
or YYY lbs. Otherwise, damage to the
vehicle and unstable driving situations
may result.2.Determine the combined weight of the
driver and passengers that will be riding in
your vehicle.3.Subtract the combined weight of the driver
and passengers from XXX kilograms or
YYY pounds.4.The resulting figure equals the available
amount of cargo and luggage load ca‐
pacity.
For example, if the YYY amount equals
1,000 lbs and there will be four 150 lbs
passengers in your vehicle, the amount of
available cargo and luggage load capacity
is 400 lbs: 1,000 lbs minus 600 lbs =
400 lbs.5.Determine the combined weight of lug‐
gage and cargo being loaded on the vehi‐
cle. That weight may not safely exceed the
available cargo and luggage load capacity

General information Your vehicle contains advanced technology for
the reduction of fuel consumption and emis‐
sions.
Fuel consumption depends on a number of dif‐
ferent factors.
Carrying out certain measures, such as a mod‐
erate driving style and regular maintenance,
can influence fuel consumption and the envi‐
ronmental impact.
Remove unnecessary cargo
Additional weight increases fuel consumption.
Remove attached parts
following use
Remove roof-mounted luggage racks which
are no longer required following use.
Attached parts on the vehicle impair the aero‐
dynamics and increase the fuel consumption.Close the windows and glass
sunroof
Driving with the glass sunroof and windows
open results in increased air resistance and
thereby reduces the range.
Tires
General information Tires can affect fuel consumption in various
ways, e.g., tire size may influence fuel con‐
sumption.
Check the tire inflation pressure
regularly
Check and, if needed, correct the tire inflation
pressure at least twice a month and before
starting on a long trip.
Low tire inflation pressure increases rolling re‐
sistance and thus raises fuel consumption and
tire wear.
Drive away immediately
Do not wait for the engine to warm-up while
the vehicle remains stationary. Start driving
right away, but at moderate engine speeds.
This is the quickest way of warming the cold
engine up to operating temperature.
Look well ahead when
driving
Avoid unnecessary acceleration and braking.
By maintaining a suitable distance to the vehi‐
cle driving ahead of you.
Driving smoothly and proactively reduces fuel
consumption.Seite 189Saving fuelDriving tips189

Tire inflation pressure Safety information
The tire characteristics and tire inflation pres‐
sure influence the following:▷The service life of the tires.▷Road safety.▷Driving comfort.
Checking the tire inflation pressure
WARNING
A tire with low or missing tire inflation
pressure impacts handling, such as steering
and braking response. There is risk of an acci‐
dent. Regularly check the tire inflation pres‐
sure, and correct it as needed, e.g., twice a
month and before a long trip.◀
Tires have a natural, consistent loss of tire in‐
flation pressure.
Tires heat up while driving, and the tire infla‐
tion pressure increases along with the tire's
temperature. The tire inflation pressure speci‐
fications relate to cold tires or tires with the
ambient temperature.
Only check the tire inflation pressure when the
tires are cold. This means after driving no more
than 1.25 miles/2 km or when the vehicle has
been parked for at least 2 hours.
The displays of inflation devices may under-
read by up to 0.1 bar/2 psi.
For Flat Tire Monitor: after correcting the tire
inflation pressure, reinitialize the Flat Tire
Monitor.
For Tire Pressure Monitor: after correcting the
tire inflation pressure, reset the Tire Pressure
Monitor.
Tire inflation pressure specifications
The tire inflation pressure table, refer to
page 206, contains all tire inflation pressure
specifications for the specified tire sizes at the
ambient temperature. The tire inflation pres‐
sure values apply to tire sizes approved by the
manufacturer of the vehicle for the vehicle
type.
To identify the correct tire inflation pressure,
please note the following:▷Tire sizes of your vehicle.▷Maximum permitted driving speed.
Tire inflation pressures up to
100 mph/160 km/h
For speeds of up to 100 mph/160 km/h and for
optimum driving comfort, note the pressure
values in the tire inflation pressure table, refer
to page 206, and adjust as necessary.

Tires with DOT codes meet the guidelines of
the U.S. Department of Transportation.
Tire age DOT … 0116: the tire was manufactured in the
1st week of 2016.
Recommendation
Regardless of wear and tear, replace tires at
least every 6 years.
Uniform Tire Quality Grading Quality grades can be found where applicable
on the tire sidewall between tread shoulder
and maximum section width.
For example: Treadwear 200; Traction AA;
Temperature A
DOT Quality Grades
Treadwear
Traction AA A B C
Temperature A B C
All passenger car tires must conform to Fed‐
eral Safety Requirements in addition to these
grades.
TreadwearThe treadwear grade is a comparative rating
based on the wear rate of the tire when tested
under controlled conditions on a specified gov‐
ernment test course. For example, a tire graded 150 would wear one and one-half, 1 g,
times as well on the government course as a
tire graded 100. The relative performance of
tires depends upon the actual conditions of
their use, however, and may depart signifi‐
cantly from the norm due to variations in driv‐
ing habits, service practices and differences in
road characteristics and climate.
Traction
The traction grades, from highest to lowest,
are AA, A, B, and C.Those grades represent the tire's ability to
stop on wet pavement as measured under
controlled conditions on specified government
test surfaces of asphalt and concrete. A tire
marked C may have poor traction performance.
The traction grade assigned to this tire is
based on straight-ahead braking traction tests,
and does not include acceleration, cornering,
hydroplaning, or peak traction characteristics.
Temperature
The temperature grades are A, the highest, B, and C, representing the tire's resistance to the
generation of heat and its ability to dissipate
heat when tested under controlled conditions
on a specified indoor laboratory test wheel.
Sustained high temperature can cause the ma‐
terial of the tire to degenerate and reduce tire
life, and excessive temperature can lead to
sudden tire failure. The grade C corresponds
to a level of performance which all passenger
car tires must meet under the Federal Motor
Vehicle Safety Standard No. 109. Grades Band
A represent higher levels of performance on
the laboratory test wheel than the minimum re‐
quired by law.
WARNING
The temperature grade for this tire is es‐
tablished for a tire that is properly inflated and
not overloaded. Excessive speed, underinfla‐
tion, or excessive loading, either separately or
in combination, can cause heat buildup and
possible tire failure.◀
RSC – Run-flat tires Run-flat tires, refer to page 212, are labeled
with a circular symbol containing the letters
RSC marked on the sidewall.

Tire treadSummer tires
Do not drive with a tire tread depth of less than
0.12 inches/3 mm.
There is an increased danger of hydroplaning if
the tire tread depth is less than 0.12 in‐
ches/3 mm.
Winter tires
Do not drive with a tire tread depth of less than
0.16 inches/4 mm.
Below a tread depth of 0.16 inches/4 mm, tires
are less suitable for winter operation.
Minimum tread depth
Wear indicators are distributed around the
tire's circumference and have the legally re‐
quired minimum height of 0.063 in‐
ches/1.6 mm.
They are marked on the side of the tire with
TWI, Tread Wear Indicator.
Tire damage
General information
Inspect your tires regularly for damage, foreign
objects lodged in the tread, and tread wear.
Information Driving over rough or damaged road surfaces,
as well as debris, curbs and other obstacles
can cause serious damage to wheels, tires and
suspension parts. This is more likely to occur
with low-profile tires, which provide less cush‐
ioning between the wheel and the road. Be
careful to avoid road hazards and reduce your
speed, especially if your vehicle is equipped
with low-profile tires.
Indications of tire damage or other vehicle mal‐
functions:▷Unusual vibrations while driving.▷Unusual handling such as a strong ten‐
dency to pull to the left or right.
Damage can, e. g., be caused by driving over
curbs, road damage, or similar things.
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. If tire dam‐
age is suspected while driving, immediately re‐
duce speed and stop. Have wheels and tires
checked. For this purpose, drive carefully to
the nearest dealer’s service center or another
qualified service center or repair shop. Have
vehicle towed or transported as needed.◀
WARNING
Damaged tires can lose tire inflation
pressure, which can lead to loss of vehicle
control. There is risk of an accident. Do not re‐
pair damaged tires, but have them replaced.◀
Changing wheels and tires
Mounting Have mounting and wheel balancing carriedout by a dealer’s service center or another
qualified service center or repair shop.
Wheel and tire combination
You can ask the dealer’s service center or an‐
other qualified service center or repair shop
about the right wheel/tire combination and
wheel rim versions for the vehicle.
